I'm trying to replace the shift shaft seal on my 07 YZ 125 engine. I've read so many times that its easy to do and the seal just 'pops' out.... Well it isn't happening that easily for me...
The seal (11 in the photo below) is disintegrated and I have 2 ways of getting it out:
1) Dig at it and take it out piece by piece with a set of hooks/picks... The problem is, I dont think I'll be able to get ALL of the seal out by just picking at it. I'm afraid to aggressively dig and pull at it for fear of damaging something else... although from the looks of the photo below, The first 2 things I encounter after removing the shifter are two oil seals (numbers 7 and 11 are oil seals), both of which I have right now. After removing the surface of the seal, there's a metal ring, I don't know if this is a part of the case, or if it's a part of the seal, I'm tempted to pull at it to try to get it to pop out (if it's a part of the seal), but if it's not...I could damage the case. Does anyone have any input?
2) The other option is to take the side case off, the clutch off, and pull the shift shaft out through the engine so I have more room to dig at the seal. Which is a lot of work, and I dont know if I have all of the tools.
Does anyone have any input or a similar experience? Any help would be great!
